WitrynaIn vertically upright bottles, packaged wine can be spoiled visible as an interface at the neck of the bottle. Critical acetic acid contents vary with the kind of wine – lower in dry wines (to 0.5 g l −1) and higher in sweet ones (to 1.5 g l −1). Once infected, the chemical composition of musts/wines change with the increase of population. Witryna15 lip 2024 · A high nitrogen content in musts seems to induce a higher and/or more easily released organic nitrogen content in the wine. From an aromatic point of view, the combination of high levels of free amino acids and aging time can favor the production of heterocyclic aromatic compounds resulting from the Maillard reaction 5. …
